Working Principles
The 74LCX126MX is a quad bus buffer with 3-state outputs. It acts as a signal amplifier and driver, providing high-speed buffering of digital signals. The inputs (A1-A4) control the state of the outputs (Y1-Y4), which can be enabled or disabled using the output enable inputs (OE1 and OE2). When the output enable inputs are active, the outputs reflect the logic levels present at the inputs. When the output enable inputs are inactive, the outputs are in a high-impedance state.
